As a german I agree on principle, but utter lack of morals is hardly noteworthy nowadays. Any kind of large corporation has only one value: profit.

Which big corporation that operates internationally has any morals?

I wouldn't buy a VW vehicle based on their decline in quality and affordability during the last few decades alone. If you don't want to buy products that contain components or materials made by Chinese, or really, any, slave labour, you'll have a hard time buying any industrial product. Of course, the usage of slave labour by corporations needs to be stopped, but as an individual, that's hardly possible, because often you don't have any choice. This problem needs concerted action by governments, ideally with personal consequences for the people responsible.

Agreed, but you better be ready to not buy any other vehicles. They all use parts made in China.
